A2 Milk and Its Benefits
A2 milk is a type of milk with a different type of protein, the A1 beta-casein protein. It is not to be confused with whole cow’s milk and goat’s milk, both regular types of milk. A1 and A2 are proteins found in cows’ milk that differ by one small section in their molecular makeup. Almost all cows produce both types of casein, but there are some breeds of cattle that produce only one or the other. Cows with mainly type A1 protein (about 87% to 98%) are called “A1 cows”, while those which mainly produce type A2 protein (about 2% to 14%) are known as “A2 cows”. Here are the A2 Milk and Its Benefits, Difference Between Regular and A2 Milk.
A2 milk is available in all the same places as regular milk, but some folks might have a hard time finding it. You can usually find A2 milk in health food stores or online at specialty websites. “It’s there,” says Jean Ann Seidel, president of the Wisconsin Milk Marketing Board and a consultant for many local farm co-ops. “But it’s not easy to find.” The reason? Few people buy A2 milk as primarily a dairy product. A2 Milk and Its Benefits
In America, A1 cows are primarily raised by small farms, with many of them specializing in organic farming and grass-fed beef production. A2 milk is therefore primarily marketed to consumers who have an interest in the wholesomeness of their food and the nutritional benefits of cow’s milk. As more people learn about A1/A2 milk, according to Seidel, more products will be making their way into grocery stores. A2 Milk and Its Benefits, Difference Between Regular and A2 Milk.
Regular Milk Proteins
Regular milk contains a combination of four types of milk protein, each with its own amino acid structure. These include caseins (the largest), beta-lactoglobulin, alpha-lactalbumin, and bovine serum albumin. There are also some minor proteins like immunoglobulins that help the body fight against foreign organisms and cause allergic reactions in some people. Milk from A1 cows contains the casein with two different types of beta structures, A1 and A2. Regular milk is commonly called “A2” in academic circles, where a numerical system is used to identify the various kinds of cow’s milk. A2 Milk and Its Benefits
The Differences Between A1 and A2 Milk Proteins
Both types of beta structures are found in cows’ milk, but only the A1 structure has been shown to negatively affect human health. Research is still being done on the effects of A2 milk on people, but scientists have already discovered that there are some significant differences between regular and A2 proteins. The most notable difference is in their effect on human digestion. A2 Milk and Its Benefits
According to The New York Times, “A1 proteins form a complex with the intestinal enzyme lactase, which helps break down lactose. Since humans lack this enzyme, A1 proteins can pass through the gut undigested. When cows drink milk containing A1 protein, then the A1 is digested and fermented by bacteria in their intestines and becomes a potential source of harmful bacteria.” A2 Milk and Its Benefits
Because of this, people who can’t digest cow’s milk properly have to avoid that type of cow’s milk. This is why many people are avoiding regular milk altogether; it contains A1 casein that can be potentially harmful for those who need to consume it. Healthier people can handle regular cow’s milk just fine because they don’t have to worry about the small amount of lactose in it. A2 Milk and Its Benefits, Difference Between Regular and A2 Milk.

Academic Viewpoint of A2 Milk
Milk is a source of protein and other nutrients, but some proteins in cow’s milk have been associated with human disease. A1 beta-casein proteins are one such group. They are found in most cows and are known to be associated with type 1 diabetes, autoimmune diseases, and heart disease in humans. These diseases may be caused by a combination of many factors that include genetics and lifestyle, but studies have suggested that the A1 beta-casein protein may play an important role in causing these diseases. A2 Milk and Its Benefits
Human studies have found that A1 beta-casein proteins are recognized by the immune systems of those affected. The body then creates antibodies against these proteins. These antibodies can cause inflammation and disease in people with genetic factors that make them susceptible to autoimmune or allergic diseases. A2 Milk and Its Benefits
Although the possible effects of A2 proteins on humans are not yet well understood, many studies have found that A2 beta-casein proteins are different from A1 beta-casein proteins in both structure and function. In one study, researchers used a variety of technologies to compare both types of casein protein at the molecular level. They found several differences between A1 and A2 beta-casein protein, including:
A2 beta-casein proteins were less allergenic and were less likely to cause an allergic response in the body. The researchers found that there is a portion of A1 beta-casein protein called the N-terminal domain that is common to other known allergens, including gluten and soybean. In contrast, the N-terminal domain of A2 beta-casein proteins does not have this common feature. A2 Milk and Its Benefits, Difference Between Regular and A2 Milk. A2 Milk and Its Benefits
Another difference between A1 and A2 casein proteins is their ability to be digested by enzymes.
difference between regular and A2 milk is the way they are digested by enzymes. Beta-casein proteins from A1 cows are not degraded by digestion, while those from A2 cows are digested. The researchers found that the A1 beta-casein protein is more resistant to digestion.
Lastly, the researchers found that A2 beta-casein proteins have a different shape than regular milk protein. This difference in shape may be what makes them less allergenic, and more digestible. A2 Milk and Its Benefits
In short, A2 beta-casein proteins are likely to affect the body differently than regular milk. In a study done on mice, researchers found that A2 beta-casein proteins had fewer effects on the cells of the gut. The researchers noted that A1 beta-casein proteins cause more inflammation in the gut. This may be a reason for the negative health effects of regular cow’s milk on humans. A2 Milk and Its Benefits
Health Benefits of A2 Milk | A2 Milk and Its Benefits, Difference Between Regular and A2 Milk
While studies are ongoing, there are some promising findings from early research into the health benefits of A2 milk. The most vocal proponent of this type of milk is Dr. William Campbell, who wrote the book The G-Free Diet. Dr. Campbell claims that A1 milk is “too allergenic” for people who are sensitive to milk proteins. He has also written extensively about the benefits of A2 milk, saying that it is easier to digest and may be a better source of protein for people with lactose intolerance. A2 Milk and Its Benefits
A2 milk contains no casein proteins, so those who are sensitive to casein proteins can safely consume the A2 variant. However, it’s important not to confuse these types of milk with raw dairy like yogurt or cheese (which also contain casein). These products contain bacteria as well as other bacteria and bacteria-like organisms that can cause infections or allergies in susceptible individuals. A2 Milk and Its Benefits
A2 milk does not contain these added bacteria, but it does contain the naturally occurring bacteria found in regular milk.
A2 Milk vs A1 Milk: Which Should You Choose?
It’s important to note that although some studies say that A1 milk is dangerous for people with certain conditions, we don’t know for sure whether this is actually true. The only way to find out for yourself whether you should avoid regular dairy products or go for the A2 variety is to try it out. Many people report having fewer aversions and sensitivities after switching from regular dairy products to A2 varieties. A2 Milk and Its Benefits, Difference Between Regular and A2 Milk.

It’s also important to note that there are some other significant differences between cow’s milk and goat’s milk.
